Cough and difficult breathing are common problems in young children. The causes range from a mild, self-limited illness to severe, life-threatening disease. This chapter provides guidelines for managing the most important conditions that cause cough, difficult breathing, or both in children aged 2 months to 5 years. The differential diagnosis of these conditions is described in Chapter 2. Management of these problems in infants < 2 months of age is described in Chapter 3 and management in severely malnourished children in Chapter 7.
Most episodes of cough are due to the common cold, each child having several episodes a year. The commonest severe illness presenting with cough or difficult breathing is pneumonia, which should be considered first in any differential diagnosis.
- lymphadenopathy (generalized and localized, e.g. in the neck)

- signs associated with foreign body aspiration:
- unilateral wheeze
- area of decreased breath sounds that is either dull or hyper-resonant on percussion
- deviation of the trachea or apex beat
- signs associated with HIV infection
